The final exam will be 30 questions/30 minutes. The exam will go live on June, 10 2025 at 8:00 AM and close on June 11, 2025 at 8:00 AM (24 hour window). The exam will cover lecture slides numbers 6 through the final slideset (currently numbered 11). The book chapters 3-5 and 7 will also be covered.
All questions will be multiple choice. The exam will have embedded figures and regression tables in some of the questions where you will be asked to, among other things:
compute a standard error from available information in a regression table.
compute a t-statistics from available information in a regression table.
Be able to identify a dependent and independent variable(s) in a linear regression model as well as write out a regression model.
Assess statistical significance based on information in a regression table.
Identify and interpret: \(R^2\); \(RMSE\); \(MSE\); degrees-of-freedom as they relate to sample size; standard errors; \(t-ratios\); and \(p\)-values.
Be able to interpret regression output shown in a plot, including identifying the strength of a linear association as well as understanding what a statistically significant result might loook like in the context of a plot.
Understand what selecting on the dependent variable means
Understand the differences between observational data and experimental data are
Understand the conditions under which one may and may not ascribe a causal interpretation to a research finding
The final exam will draw heavily from the tasks you were asked to do on Project 3 so understanding what you’re doing there will help you for the exam (i.e. how to interpret regression tables, understand statistical significance, etc.). Project 3 will be due on Canvas by June 12 at 11:59 PM. No extensions will be granted and late submissions will not be graded.
